So ParMETIS crashes on the hostile platform where it is slow to debug, fine.

But your code is calling it in cases where it doesn't crash, so why not run
the same code in your friendly environment and set a breakpoint in
MatPartitioningApply() (or even the ParMETIS routine where the assert is
failing) so that you can find out where else it is being called from. This
should take about 10 seconds.
